that you can get a drop of water. bring that to the microscope and look at it and not have some pink in there, ink gonna do it, that's gonna spread out uniformly. you're not gonna get it. that ink will spread out everywhere. in the same way, if you drop that ink in the ocean of the earth, in the earth's ocean, it'd spread out too. when christopher columbus, coming across the atlantic ocean, okay, if he had taken a glass, like a 6-ounce glass that you drink water, yeah? he can reach down into the ocean and pick up that glass and then take that water and ththrow it back in, maybe tag it, maybe tag it, maybe make it all red or something, make it radioactive, somehow you can tell later on. today that glass of water all mixed up, long ago, yeah? go to the ocean, dip up, hold up to the light, it's somewhat like a little pink, because you know what? some of the atoms in christopher columbus's glass are in that glass of water.
